Manufacturing Quality Control of 3-(2-THIENYL)ACRYLIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities by HPLC separation and UV absorbance relative to the main peak. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using gas chromatography with flame ionization detection against calibration standards. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine generation in pyridine/methanol-based reagent. |
| Heavy Metals | ICP-OES | Determines total heavy metal content (e.g., Pb, Cd, Ni, Fe) after acid digestion by measuring elemental emission intensities. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate ions using anion-exchange column and conductivity detection. |
| Acid Value | Acid-Base Titration | Determines free carboxylic acid content by titration with standardized NaOH solution using phenolphthalein indicator. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of sample against established visual standards under controlled lighting. |
| Loss on Drying | Gravimetric Analysis | Determines volatile content by measuring mass loss after drying at specified temperature and time under vacuum or nitrogen. |
| Residue on Ignition | Sulfated Ash Test | Measures non-volatile inorganic residue after high-temperature ignition following sulfuric acid treatment per USP <281>. |
